'Snake in The Monkey's Shadow' (1979) – Wilson Tong.

A poor, kindly fishmonger Lung (John Cheung Ng-Long) dynamically montages into a mighty martial arts mofo after suffering an especially humiliating incident. To add further insult to injury, his beloved masters are killed by callous Kung fu fiends, and he swears to avenge their deaths in a sensationally savage, sinew snapping climax of cathartic Kung Fu ferocity! Maestro Wilson Tong's exhilarating Martial Arts banger is quite rightly lauded by the Kung Fu cognoscenti as being a prodigiously fight-packed Old School banger, and I can only humbly proffer my own praise for 'Snake in The Monkey's Shadow'.
